At the end of a long day of cutting, I just drop the bar nose into a nice pile of gravel and go full throttle. The natural abrasive action of the fine pumice-like stones hone the cutters to a razor sharp edge that is second to none. Keep wasting your $$$ on files and grinders you suckers......:jester:
Hey, I tried this method today and it didn't work. What size of gravel do you use?
